About
I am a Doctoral student at the Indian Institute of Science (IISc), Bangalore, specializing in Data-driven modelling and Complex systems theory within the Aerospace domain. I currently work in Combustion Physics Lab under the guidance of Prof. Santosh Hemchandra. My research focuses on uncovering the underlying physics of complex fluid flows through advanced computational methods and network theory.
I have extensive experience in high-performance computing, specifically developing and managing in-house CFD (LES/DNS) solvers primarily written in C. My technical contributions include implementing rotating overlapping meshes, periodic boundary conditions, and interfacing solvers with chemical kinetics libraries like Cantera.
